Specification of Letters Patent. PaQg/medmmm ,307.3191A application met August 29,1914. semi no. 859,139.

To all whom it may concern Be it known that I, Asa B. Hansis, a citi zen of the United States, residing at Vienna, in thecounty of Johnson and State of Illinois, have invented new and useful Improvements in Tilling-Machines, of which the following is a specification.

Thisv invention relates to soil til-ling ina-` chine's, and it has for its"object to produce a` tilling machine having a rotary element of simple and improved constructionwhich may be used for breaking, crushing and agitatmg the soil, leaving roots and trash eX posed Ion the surface where it will quickly decay and form a nutrient for the soill and also loosening .the soil to a considerable depth in order that it may be well fitted to' retain moisture, thereby producing a machine which will be peculiarly fitted for operation on the hillsides where ordinarily the precipitation will be carried oi, therebynot only losing the benefits of the moisture, but also involving the loss of valuable soil that Iis apt'to be carried` away by freshets.

yA further object of the invention is to produce a machine having a rotary element of the class described which may be readily converted into a roller that ,may be used for the purpose of packing and compacting the soil.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same con.

sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying 'drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precisestructural details therein exhibited,

but that changes, alterations and modiiications Within the scope of the claim may be resorted to when desired.

In the drawings,`Figure 1 is a plan View of a machine constructed in accordance with the invention. Fig'. 2 is a side elevation of the same. Fig. 3 is a sectional view taken longitudinallyV through therotary element on the line 3-3 in Fig. 1. Fig., l is a side elevation showing the machine converted into a roller. Fig. 5 is a perspective detail view of one of the cylinders used in the ,construction of the device. Fig. 6 is a perspective detail View of one oi' the blades.

Fig. 7 is a horizontal sectional view taken on the line 7-7 in Fig. 2.

Corresponding parts in the several Egures --are denoted by like characters of reference. v

A. rectangular frame 15 which is constructed prefer blyof channel iron .is pro vlded with a 1 ar axle 16 having ground Wheels 17, the front endv of the liframe being supported on a vtruck 18 with which it .is

connected by a king bolt 19 to provide for the convenient steerlng of themachine. The side members of the trarne su ort upright guides 2 0 which are reinforced l said guides being equipped with vertically slidable boxes or bearing members 22 for vthe vertical adjustment of which screws 23V having nuts 24 are provided. rhe boxes afford bearings for a shaft 25 having at one end a collar or flange 26, the otherend belng provided .with a thereon for-the purpose of retalnin in po' sition a plurality ofcylinders-28 which are mounted on said shaft. are made of heavy material,.such as cast iron, and eachA is provided 'lvith an axiai bore 29 engaging the shaft; each cylinder also provided in the endilfaces thereoi2 with recesses 30 arranged in ra ial series.

The cutting blades 3l, w ich are adapted i sembling the parts of the device for operation, the cylinders 28 are' mounted on the The cylinders 28 COPY nut 27 threaded i shaft alternately with the blades, a set or' blades being arranged between the opposed faces of adjacent cylinders. After a proper number of cylinders and blades have been mounted on the shaft, the nut 27 is applied thereto and tightened, after which the shaft may be mounted :tor operation in the bearing members 22. j

By manipulating the nuts t on the screws 23 attached to the bearing members, the latter may be raised orlowered with retated by engagement of the teeth with the' soil and the latter being broken, crushed and agitated by the progress of the machine. It is also evident that the roots, stalks and other trash remaining from previous crops will be left exposed on the surface of the ground Where it will quickly decay, thus forming a valuable fertilizing material.

By the operation of this machine the soil l will be cut and agitated toa considerable depth, and an excellent seed bed will be .formed in addition to which the soil sub. jected to the action of the machine will be left in excellent condition for the retention of moistre '0 By removing the blades from the rotary In a machine ofl the class described, a rotary element comprising 'a shaft, a plurality of cylinders mounted thereon, said cylinders being provided with radially disposed series of recesses in the end'faces thereo, and ap-` proximatelyV diamond-shaped blades arranged betwren the opposed faces of the cy1- inders, said blades being provided with transverse pins engaging the recesses in the end faces ofthe cylinders. `V

In testimon whereof I ailix my signature V'fin presence o two witnesses.
